RELATED APPLICATIONS

This is a continuation of U.S. patent application Ser. No. 13/867,040, filed on 2013/04/20, which is a continuation of U.S. patent application Ser. No. 12/833,014, filed on 2010/07/09, now U.S. Pat. No. 8,447,819.

This application is related to the following commonly owned U.S. patent application, the entire disclosure being incorporated by reference herein: application Ser. No. 12/833,016, filed on Sep. 7, 2010, entitled “Methods, Systems, and Program Products for Referencing an Attachment in a Communication”.

BACKGROUND

While receiving attachments in a network communication, such as email, is common, most attachments received are unsolicited or unrequested. To request a resource in an attachment, a user typically sends the request as voice and/or text data in a voice and/or text message heard and/or read by another user. The request may be as vague or as specific as the language used by the requesting user. The other user must interpret the request and find a resource that seems to match the request. The other user in many cases locates a “matching” resource using a program or application other than the communications agent that received the request. For example, a search program may be used to search a hard-drive by the other user. The other user must enter the search criteria.

Accordingly, there exists a need for methods, systems, and computer program products for processing a request for a resource in a communication.

The term “attachment” as used herein refers to a portion of a communication that includes data from one communicant to another other than data in the message portion. A resource sent as an attachment is data that is typically not presented “inline” or in a message included in a message portion of a communication. Email attachments are perhaps the most widely known attachments included in communications. An email attachment is a file or other resource sent along with an email in a portion of the email separate from a message portion. As defined, other types of text communications as well as voice and video communications may include attachment portions. A communication may include one or more resources as one or more attachments.

The components of a user interface are generically referred to herein as user interface elements. More specifically, visual components of a user interface are referred to herein as visual interface elements. A visual interface element may be a visual component of a graphical user interface (GUI). Exemplary visual interface elements include windows, textboxes, sliders, list boxes, drop-down lists, spinners, various types of menus, toolbars, ribbons, combo boxes, tree views, grid views, navigation tabs, scrollbars, labels, tooltips, text in various fonts, balloons, dialog boxes, and various types of button controls including check boxes and radio buttons. An application interface may include one or more of the exemplary elements listed. Those skilled in the art will understand that this list is not exhaustive. The terms “visual representation”, “visual component”, and “visual interface element” are used interchangeably in this document. Other types of user interface elements include audio output components referred to as audio interface elements, tactile output components referred to as tactile interface elements, and the like.

A “user interface (UI) element handler” component, as the term is used in this document, includes a component configured to send information representing a program entity for presenting a user detectable representation of the program entity by an output device, such as a display. A “program entity” is an object included in and/or otherwise processed by an application or executable program component. The user detectable representation is presented based on the sent information. The sent information is referred to herein as “presentation information”. Presentation information may include data in one or more formats including image formats such as JPEG, video formats such as MP4, markup language data such as HTML and other markup based languages, and/or instructions such as those defined by various script languages, byte code, and/or machine code. For example, a voice communication for receiving by a communications agent and/or for sending by a communications agent may be included in a media container having a specified format, such as MPEG4, and may be compressed, encrypted, and/or otherwise encoded. The data is communicated for presenting in and/or by one or more user interface elements included in a user interface of a communications agent included in the communication. Components configured to send information representing one or more program entities for presenting particular types of output by particular types of output devices include visual interface element handler components, audio interface element handler components, tactile interface element handler components, and the like.

A representation of a program entity may be presented and/or otherwise maintained in a presentation space. As used in this document, the term “presentation space” refers to a storage region allocated and/or otherwise provided for storing presentation information, which may include audio, visual, tactile, and/or other sensory data for presentation by and/or on an output device. For example, a buffer for storing an image and/or text string may be a presentation space. A presentation space may be physically and/or logically contiguous or non-contiguous. A presentation space may have a virtual as well as a physical representation. A presentation space may include a storage location in processor memory, secondary storage, a memory of an output device adapter device, and/or a storage medium of an output device. A screen of a display, for example, is a presentation space.

As used herein, the terms “program”, “program component”, “application”, “application component”, “executable”, and “executable component” refer to any data representation that may be translated into a set of machine code instructions and optional associated program data. Thus, a program or executable may include an application, a shared or non-shared library, and a system command. Program representations other than machine code include object code, byte code, and source code. Object code includes a set of instructions and/or data elements that either are prepared for linking prior to loading or are loaded into an execution environment. When in an execution environment, object code may include references resolved by a linker and/or may include one or more unresolved references. The context in which this term is used will make clear that state of the object code when it is relevant. This definition includes machine code and virtual machine code, such as Java™ byte code.

Various user interface elements illustrated in FIG. 7 a presented by communications agent 503 may be presented by one or more user interface element handler components 511. User interface element handler component(s) 511 in FIG. 5 may send presentation information representing visual interface element(s), such as sender UI element 704 a in FIG. 7 a, to GUI subsystem 515. GUI subsystem 515 may instruct graphics subsystem 517 to draw the visual interface element(s) in a region of an output device, included in execution environment 501 of a node, based on the presentation information received in and/or generated from data received in the communication.

Input may be received via input driver 519 in FIG. 5. For example, a user may move a mouse to move a pointer presented in a display of first node 602 over send button 712 a. The user may provide an input detected by the mouse. The detected input may be received by GUI subsystem 515 via input driver 519 as a send command indicator based on the association of the shared location of the pointer and the send button 712 a in the presentation space of the display.

Data to send in a communication to a remote communications agent may be received by one or more content handler component(s) 509 to transform the data into one or more representations suitable for transmitting in the communication and/or suitable for processing by the remote communications agent. The one or more data representations may be provided to content manager component 506 for sending in the communication. Content manager component 506 may package the one or more data representations in a message formatted according to the communications protocol provided by communications protocol component 507. Content manager component 506 may alternatively or additionally encode and/or otherwise transform one or more of the data representations for sending in a data stream such as voice stream and/or a video stream for communicating in the communication to the remote communications agent.

Content manager component 506 may provide the packaged, encoded, and/or transformed data to communications protocol component 507 via com-out component 521. Com-out component 521 illustrates a component in communications agent 503 for operatively coupling communications agent 503 to communications protocol component 507 according to an interface provided by communications protocol component 507 for sending data in a communication according to a communications protocol embodied in communications protocol component 507. Communications protocol component 507 may further package and/or otherwise transform the data to send via network stack 505 for delivery via network 606 to a node including a communications agent representing a communicant in the communication.

With reference to FIG. 2, block 202 illustrates that the method includes receiving a resource criterion for requesting a resource via a first communication including a message portion including a first message addressed to a first user represented by a first node. Accordingly, a system for processing a request for a resource in a communication includes means for receiving a resource criterion for requesting a resource via a first communication including a message portion including a first message addressed to a first user represented by a first node. For example, as illustrated in FIG. 4 a, criterion handler component 402 is configured for receiving a resource criterion for requesting a resource via a first communication including a message portion including a first message addressed to a first user represented by a first node. FIG. 5 illustrates criterion handler component 502 as an adaptation and/or analog of criterion handler component 402 in FIG. 4 a. One or more criterion handler components 502 operate in execution environment 501.

FIG. 8 illustrates a criterion message 802 communicated within second node 604 for receiving a resource criterion for sending a request for a resource to a first communicant represented by a communications agent in first node 602.

A second communicant may identify a first communicant to communicate with via a communication over a network. For example, an identifier of the first communicant may be received as input from the second communicant. The identifier may be received to initiate and/or otherwise include the first communicant in a communication. In FIG. 5, presentation controller 513 and/or a UI element handler 511 for recipient UI element 706 a in FIG. 6 may receive an alias and/or communications address identifying the first communicant in response to a user input corresponding to recipient UI element handler 706 a. The user input may be detected by, for example, input driver 519. Corresponding input information may be routed to presentation controller 513 by GUI subsystem 515 as described above.

The second communicant may provide a message for exchanging in the communication via a message UI element 710 a. In FIG. 7, the second communicant may enter a message via a keyboard or other input device. The message to be sent to the first communicant may be presented, in response to detecting the message input by a UI element handler component 511 for a message UI element 710 a presented in presentation space 708 a.

Resource query dialog 722 b in FIG. 7 b may be presented by presentation controller component 513 and/or one or more UI element handler components 511. Resource query dialog 722 b may be presented in response to a user input detected corresponding to request button UI element 714 a in FIG. 7 a. Resource query dialog 722 b may be presented for receiving one or more resource criteria for requesting a resource from the first communicant via a first communications agent representing the first communicant. A resource criterion may be a name or identifier of a resource, such as a URI. A criterion may be more complex and may be expressed in a formal query language, such as structured query language (SQL), for sending to the second communication agent.

Resource query dialog 722 b illustrates attributes usable for locating one or more files. Presentation space 724 b includes a number of form UI elements for receiving one or more resource criteria by criterion handler component 502. Execution environment 501 may include a single criterion handler component 502 to receive resource criterion via resource query dialog 722 b or may include multiple criterion handler components 502. For example, execution environment 501 may include a criterion handler component 502 for each form UI element and/or may include a criterion handler component 502 for each type of form UI element.

“Match In” text box 726 b illustrates a text box for receiving a resource criterion for matching content in a resource. “Match In” text box 726 b illustrates that a resource criterion may be represented in a regular expression language. Name text box 728 b illustrates a form UI element for representing a resource name according to a file system name expression language. Name text box 728 b illustrates a resource criterion based on a “wild-card” symbol for matching one or more files or other named resources. Drop-down list UI element 730 b illustrates that a request may identify a role associated with a resource as a resource criterion for matching a user, group, and/or other nameable entity associated with a resource. “Date Modified” UI element 732 b and “Date Created” UI element 734 b illustrated various date and/or time based resource criteria for matching date and/or time attributes of a resource. Text editor UI element 736 b illustrates that a tag associated with a resource may be specified as a resource criterion. A resource criterion may be specified so that all or some of the criterion must be met for a resource.

In response to a user input corresponding to “OK” button 738 b, form data received based on resource query dialog 722 b may be received by criterion handler component 502 as a resource criterion or resource criteria. The resource criterion may be provided and/or otherwise identified to query generator component 504 to generate an attachment request for sending to the first communications agent in first node 602 along with the message received via message UI element 710 a in FIG. 7 a.

Returning to FIG. 2, block 204 illustrates that the method further includes sending, via a network to the first node, the first communication including a request portion that includes an attachment request based on the resource criterion. Accordingly, a system for processing a request for a resource in a communication includes means for sending, via a network to the first node, the first communication including a request portion that includes an attachment request based on the resource criterion. For example, as illustrated in FIG. 4 a, query generator component 404 is configured for sending, via a network to the first node, the first communication including a request portion that includes an attachment request based on the resource criterion. FIG. 5 illustrates query generator component 504 as an adaptation and/or analog of query generator component 404 in FIG. 4 a. One or more query generator components 504 operate in execution environment 501.

FIG. 8 illustrates first communication 804 including an attachment request in a request portion of first communication 804. FIG. 8 illustrates second node 604 sending first communication 804 and first node 602 receiving first communication 804.

A query may be specified in a standard query language, such as structured query language (SQL). In an aspect, query generator component 504 may represent a specified resource criterion in an attachment request based on capabilities of a first communications agent identified via a previous communication between first node 602 and second node 604.

In response to an indication to initiate a communication and/or to otherwise send data in a communication, message data whether voice, text, and/or image data may be sent by communications agent 503 in second node 604 via communications protocol component 507 for delivery to the first communications agent representing the identified first communicant. For example, a user input corresponding to send button 712 a may be received by presentation controller component 513 via input driver 519 and GUI subsystem 515 as described above. Presentation controller component 513 may provide one or more portions of data to send in the communication to one or more content handlers according to the types of the one or more portions. For example, a text message may be provided to a text/plain content handler 509 for processing content types having text/plain and/or text/* MIME type identifiers. Query generator component 504 may include and/or may be included in a content handler instructed to process resource criterion information received from one or more criterion handler component 502 into an attachment request included in a request portion of the communication to be sent.

One or more representations of the attachment request may be generated based on the resource criterion. Query generator component 504 in FIG. 5 may format, encode, and/or otherwise transform the received resource criterion information into an attachment request in a format suitable for first node 602. FIG. 9 a illustrates email communication 900 a. Email communication 900 a is illustrated formatted as a multipart/mixed content type including request portion 902 a. Request portion 902 a may be identified as a request by its location in the communication and/or by its content type. A request portion content type may be detected based on content included in the message and/or based on metadata such as content-type header 904 a identifying a MIME type identifier, such as “application/attachment-query”, defined for representing one or more resource criteria in an attachment request. The “application/attachment-query” MIME type identifier is exemplary. Other MIME type identifiers exist that may be defined to identify an attachment request, and new MIME type identifiers for identifying a request portion in a communication may be defined.

A content type identifying a request portion may be included in a representation of an attachment request. For example, a content handler 509 may be configured to detect a request portion based on detecting valid XQuery and/or SQL content, as described above. A content type identifier may be a position and/or location in a communication. The position or location may be absolute or relative. For example, a schema for a communication may define that a request portion in a communication is included in the communication at the end of the communication. There may be one or more request portions at the end. In another aspect, a schema for a communication may specify that a portion of a communication following a message portion is a request portion. Other request portions may follow. If no attachment request is included, the request portion may include no content or may include an indicator that no attachment request is included.

FIG. 9 a illustrates that “application/attachment-query” MIME type identifier may identify a schema for an XML-based language for specifying attachment-query documents. FIG. 9 a illustrates attachment-query document 906 a. Attachment-query document 906 a includes criterion tag elements 908 a corresponding to the form elements in FIG. 7 a. A criterion tag element 908 a identifies a resource criterion name, such as “content” indicating that the criterion is associated with the content of a resource. A criterion tag element 908 a also identifies a criterion type, such as “regex” indicating that the criterion is represented according to a particular regular expression language. A criterion tag element 908 a identifies a value for matching according to the type of the criterion. FIG. 9 a illustrates “and” tag 910 a indicating that all the resource criteria must be met for identifying a resource. An “or” tag (not shown) may be defined by a schema for attachment-query documents. Other operator elements and operator precedence may be defined by the schema. Grouping elements for managing operator precedence, such as parenthesis element, may be defined by the schema.

A request portion generated by query generator component 504, along with a message portion and any other data to include in the communication, may be provided and/or otherwise identified to content manager component 506 for sending in the communication. Content manager component 506 and com-out component 521 may further package and/or transform the data so that it is suitable for sending in the communication. Com-out component 521 may provide the resource portion, the message portion, and any other data for sending in the communication in representations suitable for sending by communications protocol component 507 to the first communications agent in first node 602 in first communication 804 in FIG. 8.

With reference to FIG. 3, block 302 illustrates that the method includes receiving, via a network by a first node, a first communication including a first message addressed to a first user. Accordingly, a system for processing a request for a resource in a communication includes means for receiving, via a network by a first node, a first communication including a first message addressed to a first user. For example, as illustrated in FIG. 4 b, com-in component 412 is configured for receiving, via a network by a first node, a first communication including a first message addressed to a first user. FIG. 5 illustrates com-in component 512 as an adaptation and/or analog of com-in component 412 in FIG. 4 b. One or more com-in components 512 operate in execution environment 501.

The communication illustrated by first communication 804 in FIG. 8 may be received by a communications agent in first node 602. The first communication may be delivered to first node 602 based on an address of the communications agent identifying a first communicant represented by the communications agent 503 instance of first node 602. Communications agent 503 may represent other communicants having other addresses. The address in first communication 804 indicates that the content of first communication 804 including a message portion is addressed to the first communicant.

The first communication illustrated by first communication 804 in FIG. 8 may be received in one or more packets via network 606 by network stack 505 and communications protocol component 507 in an instance of and/or analog of execution environment 501 including and/or otherwise provided by first node 602. The data in the communication may be received by com-in component 512. Com-in component 512 may provide the data to content manager component 506. Content manager component 506 may determine one or more content types of the data. The content and/or portions of the content may be provided to one or more content type handler components 509 based on the one or more content types identified by content manager component 506. For example, FIG. 9 a illustrates message portion 912 a including “text/plain” MIME type identifier 914 a as a content type identifier. Message portion 912 a may be provided to a text/plain content handler 509. Audio data in a voice communication may be provided to an audio content handler component 509, and video data in a video communication may be provided to a video content handler component 509.

Returning to FIG. 3, block 304 illustrates that the method further includes detecting, by the first node, an attachment request included in the first communication. Accordingly, a system for processing a request for a resource in a communication includes means for detecting, by the first node, an attachment request included in the first communication. For example, as illustrated in FIG. 4 b, query content handler component 414 is configured for detecting, by the first node, an attachment request included in the first communication. FIG. 5 illustrates query content handler component 514 as an adaptation and/or analog of query content handler component 414 in FIG. 4 b. One or more query content handler components 514 operate in execution environment 501.

FIG. 8 illustrates detect message 806 communicated within first node 602 for detecting one or more attachment requests for locating the resource.

Content manager component 506 may detect content type information described above to detect a request portion of a communication. For example, the content illustrated in FIG. 9 a may be received in first communication 804. Content manager component 506 may detect “application/attachment-query” MIME type identifier in content-type header 904 a. The “application/attachment-query” MIME type identifier may be defined to identify an attachment request based on one or more resource criteria for identifying a requested resource. Content manager component 506 may identify request portion 902 a as including the attachment request.

In response to detecting an attachment request in first communication 804, content manager component 506 may provide the attachment request and/or a resource criterion identified to query content handler component 514. For example, query content handler component 514 may be configured to operate according to a schema defining a format and/or a vocabulary for an XML-based language for attachment-query documents. Communication manager component 506 may provide attachment-query document 906 a, as an attachment request, to query content handler component 514. Query content handler component 514 may operate according to an attachment-query schema. In an aspect, a query content handler component may process more than one attachment request content type. Alternatively or additionally, execution environment 501 may include multiple query content handlers 514 for supporting multiple attachment request content types.

FIG. 7 c illustrates a user interface presented by a communications agent for presenting data received in a communication with another communications agent. Communication receive window 752 c may be presented by presentation controller 513 and/or one or more UI element handler components 511 operating in an instance, adaptation, and/or analog of execution environment 501 including and/or otherwise provided by first node 602. “From” UI element 754 c may include an identifier of the second communicant responsible for sending first communication 804. “To” UI element 756 c may include an identifier of the first communicant represented by the first communications agent in first node 602 illustrated by communications agent 503 in FIG. 5. Text, image, and/or video content received in the communication may be presented in content pane 760 c in presentation space 758 c of communication receive window 752 c. User interface controls for managing the communications and/or content received in the communication may be represented by various types of UI elements.

In FIG. 7 c, communication receive window 752 c illustrates delete button 762 c for receiving an input to delete content received in first communication 804, reply button 764 c for creating and/or sending data in a second communication in reply to the received first communication 804, locate button 766 c for locating a resource based on attachment-query document 906 a detected in request portion 902 a in first communication 804, and a save button 768 c for saving the message portion and other content received in first communication 804 in a particular folder and/or location in a data store in the execution environment of first node 602. When an attachment request is not detected, locate button 766 c may be presented as inactive or not presented in second communication receive window 752 c.

Returning to FIG. 3, block 306 illustrates that the method yet further includes locating a resource based on the attachment request. Accordingly, a system for processing a request for a resource in a communication includes means for locating a resource based on the attachment request. For example, as illustrated in FIG. 4 b, resource location component 416 is configured for locating a resource based on the attachment request. FIG. 5 illustrates resource location component 516 as an adaptation and/or analog of resource location component 416 in FIG. 4 b. One or more resource location components 516 operate in execution environment 501.

FIG. 8 illustrates locate message 808 communicated within first node 602 for initiating a search and/or otherwise for locating a resource based on the attachment request.

In an aspect, communications agent 503 in FIG. 5 may invoke resource location component 516 automatically to locate one or more resources based on an identified resource criterion in an attachment request and in response to detecting an attachment request in a communication. In another aspect, communications agent 503 may invoke resource location component 516 automatically to locate one or more resources based on an attachment request in a communication in response to detecting an indication to present, via a output device, some or all of a message received in a message portion of the communication. Resource location component 516 may be invoked and/or may operate based on the attachment request and/or resource criterion identified to locate a resource prior to, during, and/or after other content received in the communication is processed. Processing may include, for example presenting a message included in the message portion in message UI element 760 c in FIG. 7 c in communication receive window 752 c.

In another aspect, communications agent 503 operating in first node 602 may present a UI control, such as locate button 766 c, to receive an instruction from the first communicant to locate a resource based on an attachment request. Alternatively or additionally, communications agent 503 may identify a resource based on an attachment request via resource location component 516 in response to detecting user input for replying, forwarding, and/or otherwise responding to the received communication. Presentation controller component 513 may receive input information in response to a detected user input that corresponds to reply button 764 c. Presentation controller component 513 may interoperate with resource location component 516 to identify one or more resources that match a resource criterion identified by the attachment request prior to, during, and/or after the first communicant provides message content for the reply. Alternatively or additionally, communication receive window 752 c or an analogous user interface may be presented for receiving data to send in a second communication in reply to first communication 804. The user interface for replying to first communication 804 may include locate button 766 c and/or an analogous UI control for receiving an indication from the first communicant to locate a resource based the attachment request.

The method illustrated in FIG. 2 may include additional aspects supported by various adaptations and/or analogs of the arrangement of components in FIG. 4 a. As described above, in one aspect a resource may be located automatically in response to detecting the attachment request. In another aspect, locating a resource may include presenting a locator UI element representing an attachment request. Locate button 766 c in FIG. 7 c exemplifies one type of locator UI control. Locate button 766 c may be presented by presentation controller component 513 as described above. A user input corresponding to a locator UI control, such as locate button 766 c, may be detected by presentation controller component 513. Presentation controller component 513 may instruct resource location component 516 to locate the resource based on an attachment request represented by the locator UI control.

In another aspect, a locator UI element may be presented to receive one or more additional resource criteria from a user. Based on the locator UI element and input from the user, resource location component 516 may receive criterion information identifying an additional criterion. Resource location component 516 may locate one or more resources in response to receiving the additional criterion. For example, a resource criterion may identify a resource file name, such as “febAccounts.xlsx”. A file locator dialog may be presented by presentation controller component 513 including a representation of the file name. The file locator dialog may be presented to receive input for navigating to a directory or folder including a file with a matching file name. Based on user input, a folder and/or directory is identified as an additional resource criterion.

In another example, a request may include a resource criterion that matches files that include content with a content type matching text/plain MIME type identifier and that were created in the last seven days since the communication including the attachment request was received. A locator dialog may be presented including representations of all files in a node that match the resource criteria. User input to select for inclusion and/or select for exclusion identifies an additional criterion that identifies at least a portion of the files represented in the locator UI element.

Returning to FIG. 3, block 308 illustrates that the method additionally includes sending, to a second node, a second communication including the located resource, as an attachment, and including a second message addressed to a second user. Accordingly, a system for processing a request for a resource in a communication also includes means for sending, to a second node, a second communication including the located resource, as an attachment, and including a second message addressed to a second user. For example, as illustrated in FIG. 4 b, the access director component 418 is configured for sending, to a second node, a second communication including the located resource, as an attachment, and including a second message addressed to a second user. FIG. 5 illustrates access director component 518 as an adaptation and/or analog of access director component 418 in FIG. 4 b. One or more access director components 518 operate in execution environment 501.

FIG. 8 illustrates second communication 810, including the resource located based on the attachment request, sent by first node 602. The resource is included as an attachment in second communication 810 to a second message included in a message portion of second communication 810. FIG. 8 illustrates second communication 810 received by second node 604.

Resource location component 516 may identify to access director component 518 one or more resources in a data base, a file system, and/or other resource data store based on the attachment request. Access director component 518 may identify a service for generating and/or accessing a resource. Access director component 518 may interoperate with the service to generate and/or otherwise access the located resource(s). A data store and/or service accessed by access director component 518 and/or by a component operating on behalf of access director component 518 may be included in the execution environment of first node 602. A data store and/or service accessed by access director component 518 may be included in an execution environment of another node and accessed via network 606.

In response to accessing a resource located by resource location component 516, access director component 518 may provide and/or otherwise identify the resource to a suitable content handler component 509 based on a content type of the resource. The content handler component 509 may decode, encode, reformat, translate, and/or otherwise transform the resource for including in second communication 810.

FIG. 9 b illustrates communication 900 b that may be communicated in second communication 810. Second message portion 902 b illustrates a message portion in second communication 810. Note that a message portion may be empty as illustrated by message portion 902 b. Attachment portion 904 b illustrates the resource as image data encoded for sending in a text-based communication.

Message portion 902 b and attachment portion 904 b may be provided by respective content handler components 509 to content manager component 506. Content manager component 506 may construct the content as illustrated in FIG. 9 b and/or otherwise provide for encoding, translating, combining, and/or otherwise preparing the content for sending in second communication 810. As described above, communication manager component 506 may send second communication 810 via com-out component 521 communicatively coupling content manager component 506 to communications protocol component 507 and/or network stack component 505 for sending second communication 810 via network 606 to second node 604 addressed to the second communicant represented by the communications agent operating in second node 604.

Returning to FIG. 2, block 206 illustrates that the method yet further includes receiving, by a second node representing a second user, a second communication including, based on the request portion, the resource, as an attachment, and a second message addressed to the second user. Accordingly, a system for processing a request for a resource in a communication includes means for receiving, by a second node representing a second user, a second communication including, based on the request portion, the resource, as an attachment, and a second message addressed to the second user. For example, as illustrated in FIG. 4 a, content manager component 406 is configured for receiving, by a second node representing a second user, a second communication including, based on the request portion, the resource, as an attachment, and a second message addressed to the second user. FIG. 5 illustrates content manager component 506 as an adaptation and/or analog of content manager component 406 in FIG. 4 a. One or more content manager components 506 operate in execution environment 501.

Data sent in second communication 810, by first node 602, may be received by com-in component 512 operating in an instance, adaptation, and/or analog of execution environment 501 including and/or provided by second node 604. The received communication includes a message addressed to the second communicant and an attachment including the resource located based on the attachment request identified by first communication 804. Content manager component 506 may detect the message portion, such as message portion 902 b in second communication 810. Content manager component 506 may detect an attachment portion, such as attachment portion 904 b in second communication 810. Message portion 902 b and attachment portion 904 b may be provided to suitable content handler components 509 based on the content types of the message portion and the attachment portion detected by content manager component 506.

In an aspect, an attachment portion that is a response to an attachment request sent in a previous message may include information identifying the attachment as a response. For example, an attachment request may be sent with a correlator and a located resource received in an attachment may identify the correlator to identify the attachment as a response to the particular attachment request previously sent.

In an aspect, accessing a resource received in response to an attachment request includes presenting, via an output device, an attachment user interface control representing the resource. In response to detecting a user input corresponding to the attachment user interface control, the resource may be accessed. One or more content handler components 509 may process data received in second communication 810 to represent that data in a format for presenting to the second communicant. Communication receive window 782 d in FIG. 7 d illustrates user interface components for presenting the message, to the second communicant, received in second communication 810. Communication receive window 782 d is similar to first communication receive window 752 b, but includes an attachment(s) UI element 798 d based on the attachment portion in second communication 810.

In an aspect, access handler component 523 may be invoked to access the resource in response to a user input corresponding to attachments button 798 d. For example, an input driver component 519 may detect an input and GUI subsystem 515 may associate the detected input with a location in a display where attachments button 798 d is presented. GUI subsystem 515 may invoke presentation controller component 513 and/or a UI element handler component 511 associated with attachments button 798 d to process the detected user input. Access handler component 523 may retrieve the resource from the communication. The content of the communication may be stored in one or more data stores accessed via one or more data storage systems, such as file system/DBMS component 525 and/or a processor memory included in execution environment 501 of second node 604.

In another aspect, the resource may be accessed automatically without receiving an indication from the second communicant to access the resource. For example, content manager component 506 may detect the attachment portion in the content received in second communication 810. Content manager component 506 may provide a representation of the resource included in the attachment portion to access handler component 523 in response to detecting the access information. Access handler component 523 may decode, reformat, translate, and/or otherwise transform the representation of the resource for presenting to the second communicant and/or for storing in a location in a data store accessed via a storage subsystem.

The method illustrated in FIG. 2 may include additional aspects supported by various adaptations and/or analogs of the arrangement of components in FIG. 4 a. The method illustrated in FIG. 3 may include additional aspects supported by various adaptations and/or analogs of the arrangement of components in FIG. 4 b. In one aspect, the first communication in the method illustrated in FIG. 2 and in the method illustrated in FIG. 3 may include a text message, an email, audio data, an instant message, and/or image data. In another aspect, the attachment request may be represented according to a criterion schema. The criterion schema defines a format for representing the attachment request and/or defines a vocabulary of valid values includable in the attachment request. Query generator component 504 may generate an attachment request according to a criterion schema and query content handler component 514 may determine whether an attachment request is valid according to the schema. Query content handler component 514 may also identify an attachment request based on a criterion schema and/or identify a resource criterion in the attachment request based on a criterion schema.

A criterion schema may be identified by a schema identifier, such as a MIME type identifier and/or a URI. Second node 604 may receive a criterion schema identifier sent from first node 602 prior to sending first communication 804. Alternatively or additionally, a schema may be preconfigured in a communications agent. For example, a content handler component 509 may operate on a request portion of a communication according to a schema for specifying an attachment request. The rules of the schema may be read from a configuration data store and/or may be included in one or more instructions in the attachment request content hander component 509. Query content handler component 504 and/or query content handler component 514 may receive a criterion schema from any of the sources described and/or any other suitable sources.

In another aspect, one or more resource criteria may be predefined. A resource criterion may be defined by a criterion schema and/or may be defined, for example by a user, according to a criterion schema. One or more resource criteria may be included in an attachment request expression or condition. Some or all of the attachment request expression or condition may be predefined, generated by query generator component 504, and/or generated based on user input. Second node 604 may receive a predefined attachment request and/or a predefined attachment request condition sent from first node 602. A predefined criterion and/or condition allows the first node to restrict and/or otherwise control attachment requests and/or may be provided for the convenience of communicants in specifying attachment requests.

As described above with respect to the method illustrated in FIG. 2, an attachment request may be received via a user interface element including a form element. In an aspect, an attachment request may specify a form element. For example, an attachment requested by a second communicant of second node 604 may be information known to a first communicant of first node 602. An attachment request may specify a user interface element including a form element. Locating the resource by first node 602 may include presenting the user interface element and receiving input from the first communicant corresponding to the form element. The resource sent by first node 602 as an attachment in second communication 810 may include information that corresponds to the form element and that is based on the input received from the first communicant. Exemplary user interface elements that may include and/or may be included in form elements include a window, a textbox, a slider, a list box, a drop-down list, a spinner, a menu, a menu item, a toolbar, a ribbon, a combo box, a tree, a grid, a navigation tab, a scrollbar, a label, a tooltip, text in various fonts, a balloon, a dialog box, and/or a button.

An attachment request may be based on a date, a time, a length of time, a file type, a database record key, content of the resource, a content type identifier, a format rule, a vocabulary, a role of a user, a security attribute, a location in a data storage system such as a file system, an attribute of an identified resource, a size, a task, a transaction, a state, a user, a group, a requester, a relationship including a requesting user and a responding user, a keyword, a tag, a folder, and/or a path portion of a resource identifier, to name a few examples.

As described above, a matching condition may include and/or otherwise identify an attachment request. A located resource must meet the matching condition in an aspect. Alternatively or additionally, an attachment request may include an instruction and/or input for generating a resource, and locating the resource may include generating the resource. Generating a resource may include creating the resource and/or may include modifying and/or otherwise transforming an existing resource.

In the method illustrated in FIG. 2, sending a first communication may include storing a criterion content type identifier in the first communication, as illustrated by content-type header 904 a in FIG. 9 a. Analogously, detecting an attachment request in the method illustrated in FIG. 3 may include detecting a criterion content type identifier in a first communication to determine that a request portion in the first communication includes an attachment request. The criterion content type may be defined to indicate that the request portion includes the attachment request.

A criterion content type identifier may include a MIME type identifier. In FIG. 9 a, “application/attachment-query” in content-type header 904 a illustrates a criterion content type identifier. A MIME type identifier may identify a criterion schema and/or a schema for a request portion and/or an attachment in a request portion. A criterion content type identifier may be any detectable information that identifies any of a criterion schema and/or a schema for a request portion and/or an attachment in a request portion.

In various aspects, a resource criterion may be detected and/or represented based on various syntaxes, grammars, vocabularies, and/or languages. For example, a resource criterion may be identified and/or represented according to a file system search syntax, a regular expression language, a structured query language (SQL) query, a universal resource identifier schema, an XPATH based language, an XQuery based language, an XML based language, an HTML based language (form-based), and/or a keyword-value pair based language.

A request portion including an attachment request in a communication may be received by a first communicant and sent on behalf of a second communicant via a first communications protocol, and a message in the communication may be exchanged in the communication via a second communications protocol. For example, a message may be sent from second node 604 to first node 602 via an RTP session according to the specification of real-time transport protocol. The second communicant may send an attachment request in the communication session via a request-reply protocol such as specified for XMPP. Both the XMPP request and the RTP session may be included in a communication.

Exemplary resources that may be requested via an attachment request include a file, a program component, a data base record, video data, audio data, markup language, binary data, text data, an output of a service. Requested resources may be pre-existing, volatile, and/or generated in response to the request.

A request portion in a communication may be identified and detected in the communication based on a term in a vocabulary defined by the criterion schema to indicate that the request portion includes the attachment request and/or includes a location defined by a format specification to indicate that the request portion includes the attachment request. For example, a content handle component 509 may be configured to detect the <attachment-query> tag in attachment-query document 906 a in FIG. 9 a. Content handler component 509 may detect and/or otherwise identify attachment-query document 906 a as a request portion. Content handler component 509 may be configured to detect an “application/attachment-query” MIME type identifier in a content-type header, or it may be configured not to detect the application/attachment-query MIME type identifier while still detecting the request portion based on the <attachment-query> tag.

As described above, an attachment including a request resource may be identified and/or detected in a communication based on a content type identifier. A content type identifier for an attachment may be represented and/or detected based on an identifiable location in the communication defined to include some or all of the attachment, a detectable format of some or all of the attachment, a detectable data entity included in a vocabulary specified for the attachment, and/or a symbolic identifier defined to indicate that the communication includes the attachment.

An attachment in a communication may be sent and/or received in the communication via a first communications protocol, and a message in the communication may be, respectively, sent and/or received via a second communication protocol. As described above, a message may be communicated via voice data sent according to RTP protocol. An attachment request and a response including an attachment may be communicated according to a request/reply protocol specified by XMPP.

An attachment may be included in a communication based on a requested-attachment schema defining to the second node at least one of a format and a vocabulary for processing the attachment.
